AGlTATOR FOR MIXED ^PAlNTS.

SPECIFICATION forming part of Letters Patent No. 510544, dated December12, 1893.

Application filed February 28, 1893. Serial No. 464 126 (NO model.)

To all wwm it may concern:

Be it known that I, CHARLES JOHN MOLEN- NAN, manufacturer, of thecity'ot' Toronto, in

the county of York, in the Province of Onta-' 5 rio, Canada, haveinvented certain new and useful Improvements in Agitators for MixedFaints, of which the following is a Specifica- My invention relates toimprovements in IO agitators for mixed paints, and the object of thepresent invention is to provide an alternative means whereby thesediment which settles at the bottom in paint already mixed may beprevented from settling and stirred :5 up into the main body of thepaint and it consists essentially of providing in the bottom of thereceptacle or tank in which the mixed paint is placed a perforated maintube and perforated branch tubes extending outwardly therefrom at thebottom of the receptacle, the main tube being connected by a universalor swing joint to the end of the barrel of a pump, which is operated soas to draw continually from the paint near the surface and force itthrough the perforations of the main tube and branch tubes at the bottomof the receptacle as hereinafter more particularly explaiued.

The drawing represents a perspective view of a paint receptacle, aportion of the side being broken away and a portion of the pump being insection so as to exhibit the arrangemont and operation of my invention.

A, is the receptacle,which is partially filled with mixed paint asshown.

B, is the main tube located preferably centrally at the bottom of thereoeptacle and having extending outwardly therefrom also preferably inproximity to the bottom the branch tubes, O. The branch tubes, C, areperforated on each side and have caps at the ends which are alsoperforated as shown and the main,

tube is perforated also at each side and has caps at the end Which arealso perforated as shown. The outer 'ends of the branch tubes arepreferably braced by the wires or rods,

D, which extend around near the outside of the same as shown. The inner'end of the main tube has an are-shaped end, b, which 5 fits within theare-shaped end, e, of the pumpbarrel, E.

F, is an opening made in the side of the pump-barrel considerablybeneath 'the surface of the paint. As the surt'ace of the paint as shownin the drawing, in which the receptacle is only partially filled, isindicated by the curved dotted lines 1--2 it will be seen that theopening F, is below the surface of the paint and it will of course beunderstood that the Opening, F, is always beneath the surface of thepaint. The opening, F, is provided with a netting, f, to prevent theentrance of any foreign substance in the paint into the pump.

G, is the 'piston Which is provided with the usual opening, g, andvalve, g'. The piston, G, is fastened on the forked end of the pistonrod, H. At the upper end of the piston rod, H, I secure the guide, I, towhich is attached the lower end of the connecting rod, J. The upper endof the connecting rod, J, is secured to the end of the Crank, K,attached to the main driving spindle, L, which derives motion from thepulley, M, driven from any suitable motor.

N, is the piston valve which is situated at the lower end of the barrel,E.

O, is a cord or chain which is attached to an eye at the top of the capat the end of the main tube, B. The upper end of the cord is fastened toa cleat.

It will be seen as usual in pumps that upon the upward stroke of thepiston the pump valve will be closed while the valve in the piston Willbe open and the mixed paint from the receptacle Will flow through thesame in between the piston and the valve, and upon the downward strokeof the piston that the valve, N, will be Open and the piston valveclosed so that the liquid will be forced down through the barrel intothe main tubes and branch tubes where it will be forced through theperforations all around the bottom of the receptacle thereby tending bythe continual working of the pump to keep the sediment stirred up in thebottom of the receptacle and thus keep the mixed paint of a uniformthickness throughout. It will of course be understood that the mixedpaint is intended to be used for dipping.

When it is not desired to use the paint and the pump is stopped fromworking the main tube being swung in the' arc shaped bottom TOO end ofthe piston barrel may be raised by the cord, 0, so that the main tubeand branch tubes will be raised up into the top of the paint away fromthe bottom, and thus any danger of the holes being filled by thesediment willbe avoided. Again although I show the tubes in the formshown it will of course be understood that other forms of tubes or theirequivalents with perforations therein might be devised to aecomplish thesame result as the main and branch tubes and I wish it to he understoodthat I do not wish to be cOnfined to the eXact form of perforated maintubes and branch tubes shown. 4

Although I show the arc-shaped end, b, of the tube, B, fitting into thearc-shaped end, e, of the barrel, E, it will of course be understoodthat other forms of Couplings might be devised, which will accomplishthis result that is to say which Will enable me to raise the tubes fromthe bottom of the tank out of the sediment, which would otherwise formif left there, when the pump is not in motion and the paint is not beingused.

What I claim as my invention is-- In combination with a reeeptacle formixed paints adapted for use for dipping articles therein, means foragitating and keeping the contents stirred consisting of perforateddistributng tubes arranged On the bottom thereof, and a pump for forcingthe material through the distributing pipes, located near one side ofthe tank, whereby the interior of the said tankis practicallyunobstructed and free for the dipping of articles in the paint containedtherein, substantially as described.
